No evidence to show that the couple had pre-marital sex. They got married on 1st October 2016 and the baby arrived on 12th May 2016. Some women are usually lucky to conceive same month of marriage, so in their case, see it that way. She conceived in October and delivered of a baby more than 8months after. Such miscalculations and misconceptions hold by people should be corrected as a baby can arrive +/- 4weeks of EDD. Congrats to the family. At least, God answered their prayers without stress of fasting and going to the mountains to pray before conception happened.
